Application January 18, 1940, Serial No. 4314,431 6 Claims. (Cl. 12s-362) new and useful imapparatus adapted for My invention relates to a provement in a diathermy use in treating unhealt through the application thereto of an electric oscillatory or vibratory'current. s

Another object of the invention is the provision of an apparatus of this type whereby the body or a selected portion of the body may be to a high frequency induced current,v

subjected plus light rays and diathermyl heat waves so that a complete electrical treatment of a patientl may be effected with a single apparatus.

Another object of the invention is the provision of an apparatus whereby a short wave radio frequency induction mechanism may be utilized for the purposes oi treating unhealthy conditions of the human body.

Another object of the invention is the provision of an apparatus whereby high frequency induced current or heat units may be caused to pass through the body in its passing from one electromagnetic field to another.

- Other objects will appear hereinafter.

It is recognized that various changes and modifications may be made in the detail of structure illustrated without departing from the spirit of the invention and it is intended that such variations and modications shall be embraced within the scope hereof,

Forming a part of this specification is a drawing, in which.

Fig'. 1 is a`bottom plan view of the applicator used in the invention;

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1;

Fig. 3 is a perspective view of and its cooperating terminal;

Fig. 4 is a diagrammatic view illustrating the wiring used in the invention.

As shown in the drawing, I provide a housing the applicatorJ open end of the and embracing the coil 61 is a l from glass or other transparent material, this 'l2 is a metallic of insulation 'M to a metallic screen l5. The housing is closed by the glass closure 1B.

Secured to the bar Blof insulating material coil Tl formed Y coil being a vacuum tubing containing vapor, a

6l formed from suitable insulating material and preferably of a molded composition' material.-

Positioned within this housing 6i is an insulatof which is mounted a bar 6d of insulating material. Through the tube 63 and through this bar @d of insulating material are projecting the ends S5 and 68 of a metallic coil Sl.y To each of the ends G5 and 66 .is secured a conductor 6E and S9, respectively,

which extend through the cable l0 to a metallic terminal plug 1I.

Thehousing is open at one side and provided at its open end with the inwardly turned ange inwardly turned 'flange .5o

posed inthe circuit. In order to suitable gas, or metallic filaments therein. A metallic terminal i8 projects inwardly at each end of the transparent coil and is electrically connected'by e contacts 19 to the screen sections 'l and 15.

In the diagrammatic view I have illustrated the wiring arrangement with which the invention is that the treatment may be carried on for a definite period of time. In the circuit there is also overload relay this relay being used as a safety factor for the tubes and the transformers. A delay relay 3 to allow time 'for the rectifying tubes to heat to a safe temperature before applying the plate voltage is also `Y`intereliminate the feed-back, I have applied two fixed condensersl connected to the vfeed lines and grounded, these connected to the secondary S-3 of the transf former, a tap l being interposed between the secondary S-S and theprimary P-S. A choke coil'` 8 connects to the secondary S-S and also screen Il connected by a layer I 9, one side of which is voltage which may be built up and which is reresistance 28a and also to the condenser 88, one l side of which is grounded as at 81y which also serves to ground the resistor 88. The plate 22 of the tube 84 is connected by the wire 88 to a copper wire coil 80 which serves to form the primary of a transformer. The plate 8| of the tube 85 is connected by the Wire 82 to the coil 80, this coil also being connected at its center through the radio frequency choke coil 83 to the wire 84 leading to the ammeter 38. The wires 88 and 82 are connected by the wires 85 and 86 through the condenser 81 which is grounded as at 88. A coupler 88 serves to connect the coils |0| and |02,

the coil |0| being a coil within the oscillating coil 80 and the coil |02 being positioned within the output coil |03. This output coil |03 is connected at its opposite ends by the wires |04 and |05 through the condenser |06. One side of the coil `|08 is connected by the wire |01 to the ammeter |08 into which is adapted the plug 1| shown in Fig. 2 which is electrically connected to the cord 10. The other side of the coil |08 is connected by the wire ||0 to a metallic plate embedded in a plug |I2 of suitable insulating material such as rubber.

In operation when the mechanism is coupled -as illustrated in the diagrammatic view, the member would be located on a portion of the persons body at which location it is desired to render a treatment. The housing is then positioned on the persons body at the same location,

upon the patient being treated and the conditions obtaining. The light rays obtained from the coil 11 may extend from infra red to ultra violet. This would, of course, depend somewhat on the structure of the coil 11 and the gas or vapor contained within the coil. The use of different gaseous vapors to obtain light rays of different colors is well-known and commonly practiced in commerce today for lighting purposes. For instance, a tube containing the proper amount of mercury vapor would produce an indigo blue color, whereas a vapor mixture of mercury and helium will produce an ultra violet. The red rays may be obtained by gaseous mixtures which are commonly used in the standard light tubes now commercially sold neon" tubes and the various colors between these ranges may likewise be obtained by the luse of different gases or different mixtures of these gases.

In all of these light colors, the low candle power is especially developed so that danger of burning is eliminated while the other desired features resulting from the high frequency of vibration are still present.

In this way I have provided a simple, compact, inexpensive, and highly eillcient mechanism whereby such a combination treatment -by means of the current and the light'rays may be simultaneously given.

In this way also I have provided a means which `combines the therapeutic effects of standard the body B shown in the diagrammatic view being positioned between these terminals, so that the current will pass through the body and set up the desired reaction resulting from the passage through the body of an induced current of high oscillating frequency. The current would be induced from the coil 81 to the coil 11 and the screen 13 and 15 would constitute a distributing outlet. Thewire |01 serves as a conductor of an induced current of radio frequency. Likewise, the wire ||0 serves as a conductor of induced current of -radio frequency. By leading the wire |01`to the coil 81. this induced current y of radio frequency is again used to induce a current inthe tube 11 which delivers an induced current of radio frequency to the screens 13 and 15. In addition to this, however,`the transparent coil 11 serves as a light ray medium so that it becomes possible in the electrical treatment of. diseases of persons to, simultaneously, subject the person to the desirable effects resulting from the passage of a high frequency oscillating current through the person and at the same time to the applied eiIects of combined light ray treatment. The light rays obtained from the coil 11 are of the long Wave band and low candle power which, combined with an oscillating current of high radio frequency induced current, makes it possible to obtain the profits of light therapy at the same time `-the diathermy treatments are being administered. `The light rays obtained from the coil 11 can be varied depending upon the naturel of specic rays desired. The nature of specified rays desired will,of course, depend diathermy, solartherapy, At the same time I have provided means whereby heat and light may be simultaneously administered without the undesirable effects of burning or irritation which is commonly encountered in electrotherapeutics.
